Abstract

Graphite that had been ball-milled for 10 h in 3 bar hydrogen, was then mixed with lithium borohydride (2:1 molar ratio of graphite to LiBH₄) and milled for a further 2 h. This resulted in a significantly enhanced the hydrogen desorption properties: compared with the pure hydrogenated milled graphite, added LiBH₄ lowered the desorption temperature by 170°C, to 230°C, and increase the hydrogen desorption from 5.6 to 9.3 wt%, heating to 500°C. There was no detectable methane generation in the desorption gas.
